A certain sample of a pure quartz crystal has a mass of 276 grams and a volume 95.8cm^3.
-what is the mass density of the sample?
-what would be the volume of a larger quartz crystal of the same density if its mass is 1.138 kg?

Help please!! Have been struggling with this problem for an hour now and still can't get anywhere. Thank you!!

density = mass / volume

volume = mass/density

I would do it all in cm^3 and grams

1 kg = 1,000 grams
